NKP series video SPD is used to protect power supply, video and data devices of AC/DC-powered surveillance cameras from surge damage caused by sudden increase of potential difference between different devices when there is induction lightning strike. It is designed with advantage of large intake capacity, low residual voltage, fast response time and long lifetime.

Features

1. Three protected lines, no interference with each other; Reliable performance;

1. The power supply connection: Products should be match with protected camera power supply voltage. When it needs to install, please according diagrams to install. One of power supply line, “L ~” is fire wire or positive. “N ~” is zero line or negative.

2. The video signal connections: The input end is connected with the signal channel, the output end is connected to the video camera, and these connectors should be connected securely and not be reversed.
